High temperatures coupled with high humidity impose severe stress on birds and can cause huge economic loss. Such loss is due to reduced performance, immune suppression, and an increase in respiratory disease and mortality (Mandal, 2010). Ex ...

Various environmental stressors such as high ambient temperature and relative humidity influence the performance of broilers by reducing feed intake, feed conversion efficiency and hypophyseal-adrenocortical axis that in turn stimulates corticosterone which retarded growth (Dong et al., 2007). Reactive oxygen species (ROS) are generated at cellular level during normal bodily functions; however, hi ...
